The improvement of the co-generation plant in sugar factories and selling additional power to the national grid may be possible. This generates additional revenue in the sugar mills. The steam demand in process can be minimized by secondary power production in the co-generation plant. The secondary power production in the co-generation plant can be achieved in online process by employing extensive vapour bleeding systemat the evaporators for secondary heating of cane juice (85-110ï‚°C). The annual saving achieved was Rs.11.00million. This required an investment of Rs.6.50 million, which had an attractive simple payback period of 8 months.
